Configuration description
Handshake mode
To use RS-232 interface to communicate with PC, the equipment of both sides must negotiate a set of rules to ensure the
correct transmission of data. Such negotiation is called a handshake. Since there are many handshake modes between the
instrument and PC, it must be ensured that both the instrument and PC shall select the same method.
Options of handshake mode are as below
Data format
Data format includes the format of start bit, data bit, parity bit and stop bit. The instrument allocates four formats for the
data format.
Baud rate
Baud rate refers to the data transmission rate sent from one device to another. In unit of bits per second, the baud rate
can be set by the instrument includes 1200, 2400, 4800, 9600, 19200, 38400 and 57600.
Terminal mode
Terminal mode refers to the terminal characters used at the end of sending data. When sending data from the instrument,
"CR", "LF" and "CR+LF" can be used as terminators. When sending data to the instrument, "LF" and "CR+LF" can be used
as terminators.

Stop sending when
X-OFF is received,
and resume sending
when X-ON is
received
Stop sending when
CB (CTS) is wrong;
resume sending
when it is correct
Send X-OFF when
the receive buffer is
3/4 full; send X-ON
when it is full.
Set CA (RTS) to false
when the receive
buffer is 3/4; set CA
(RTS) to 1/4 full.
